Tonzi: 2011-11-02 10:00:00 (DOY 306)
Author: Joe Verfaillie
Others: Siyan

Summary: Checked refocused Stardot camera, fixed labels in Loggernet on floor computer, replaced flowmeter in co2 profile system, did EMI survey, cleaned z-cam windows, tree circumfrence.

Tonzi
2011-11-02

I arrived about 10:00PST with Siyan. It was clear and warm with little to no wind. The trees here have begun to loose there leaves. Many have obviously changed color. There are lots of acorns on trees and on the ground. The grass looks better here especially in the low spots. Many broad leaf herbs have sprouted.

I check on the stardot camera. Closing down the aperture improved the depth of focus so that most of the image is now in focus. The exposure is about 200.

I fixed the labels in Loggernet on the floor tower.

I did an EMI survey

I cleaned the windows on the z-cams.

I replaced the flow meter in the CO2 profile system with a new, clean one.

Siyan measure breast height circumference of tree with dendrometer rings.
